<h1 class="topictitle1">A Copy-based Restoration Job Fails When a Host Where an AIX Client Configured with LAN-Free Is Installed Is Used for DB2 Backup and Restoration</h1>
<div><div class="section"><h4 class="sectiontitle">Symptom</h4><p>When a host where an AIX client configured with LAN-free is installed is used for DB2 backup and restoration (the data protocol is iSCSI), the DB2 copy-based restoration fails, and a message is displayed, indicating that the directory fails to be mounted to the host (<em>X</em>.<em>X</em>.<em>X</em>.<em>X</em>) where the client is installed.</p>
</div>
<div class="section"><h4 class="sectiontitle">Possible Cause</h4><p>The target service on the SAN Client host or the iSCSI service on the AIX host is abnormal.</p>
</div>
<div class="section"><h4 class="sectiontitle">Troubleshooting</h4><ol><li><span>Use PuTTY to log in to the host where the AIX client is installed as user <strong>root</strong>.</span></li><li><span>Run the following command and check whether the <span class="uicontrol"><b>mountfileiosystem.log</b></span> file contains messages "Not find target fileio with lun_id xx." and "Scan disk failed, not find any disk info."</span><p><pre class="screen">vi $DATA_BACKUP_AGENT_HOME/DataBackup/ProtectClient/ProtectClient-E/slog/mountfileiosystem.log</pre>
<ul><li>If yes, log in to the SAN Client host. After ensuring that no backup or restoration service is running, run the following commands in sequence to restart the target service:<pre class="screen">systemctl stop targetcli
systemctl stop target
systemctl start target
systemctl start targetcli</pre>
<p>After the restart is complete, perform the restoration job again. If the job succeeds, no further action is required.</p>
</li><li>If not, go to the next step.</li></ul>
</p></li><li><span>Run the <strong>errpt -a | summ</strong> command and check whether the command output contains <span class="uicontrol"><b>VIOS_VSCSI_ERR3</b></span> or <span class="uicontrol"><b>ISCSISW_ERR1</b></span>.</span><p><ul><li>If yes, find the corresponding error handling solution on the <a href="https://www.ibm.com/mysupport/s/?language=en_US" target="_blank" rel="noopener noreferrer">IBM Support</a>.</li></ul>
<ul><li>If no, contact Huawei technical support engineers.</li></ul>
